| 摘要 |
The present invention relates to a data processing device and a data processing method which can ensure excellent communication quality in data transmission using LDPC codes. In groupwise interleaving, the code length N is 64800 bits, and LDPC codes with a coding rate r of 9/15, 11/15 or 13/15 are interleaved in bit group units of 360 bits. In groupwise deinterleaving, the sequence of the LDPC codes after groupwise interleaving is returned to the original sequence. This invention can be applied for example when performing data transmission, etc., using LDPC codes. |
